Interal-arm blood pressure difference with computer-programmed blood pressure measurement: difference between the first reading and the average of the second and the third readings
摘要
This study aimed to compare the inter-arm blood pressure difference (IAD) based on the first reading versus the average of the second and the third readings using computer-programmed blood pressure measurement (CCBPM) in 3067 rural community residents. The detection rate of abnormal systolic IAD (sIAD) was 9.1% based on the first reading, compared to 5.6% based on the average reading—a difference of approximately 40%. These findings suggest that CCBPM should be used with the average of the second and the third readings for sIAD evaluation.
